A Private Pricing Opinion — what your apartment at 243 East 77th Street would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
243 East 77th Street puts elevator access into a small prewar cooperative with a varied apartment mix. Conventional one-bedrooms share the building with larger garden duplexes and multi-level penthouse space. Private outdoor areas occur at both ends of the structure, including gardens, balconies and roof terraces.
The cooperative offering was accepted in July 1981 and became effective in January 1982, with Zefka Realty Inc. as sponsor. The original rehabilitation offering covered fourteen residences. Current city records carry thirteen.
Architecture and unit composition
The middle-floor apartments include one-bedroom layouts of approximately 800 to 900 square feet. Larger lower-level homes extend to roughly 1,300 square feet and can combine internal stairs with access to a private garden or balcony.
At the top of the building, penthouse space spans multiple levels with private terraces. The elevator reaches the entrance level of that configuration; stairs provide access to its other interior levels. A buyer seeking elevator access throughout a home therefore needs to distinguish the building's elevator service from circulation inside the apartment.
The range in floor plans is substantial for a cooperative this small. A conventional one-bedroom and a multi-level home involve different usable-area calculations, outdoor-space responsibilities and routes between rooms.
Building operations
The cooperative occupies a single tax lot and provides common laundry and intercom entry. Class 2 applies without assessment-growth caps, and no tax abatement is recorded. Its existing floor-area ratio exceeds the residential allowance under current R8B zoning.
The building's limited apartment count means common expenses are allocated across a small group of shareholders. The proprietary lease and share schedule determine how those charges fall on homes of different sizes, including the larger garden and penthouse configurations.
Policy framework
A seller-paid flip tax of 1.5% has been stated — confirm the current rate and calculation with the managing agent.
Pets are considered case by case; pieds-à-terre and in-unit washer/dryers are allowed — confirm with the managing agent. Apartment alterations remain subject to the cooperative's approval requirements.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01432-0017) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage on co-ops is not officially recorded, figures shown are approximate.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
